Once the equations of motion are derived (e.g., $I\ddot\theta + mgL\sin\theta = 0$ for a physical pendulum), the next step is solving them. Most Mechanics 3 problems fall into one of three categories:
This combined loading zadatak is very common in Mehanika 3 finals.
Da li je lakše koristiti dekartove, polarne ili prirodne koordinate?
Jasno razdvojite aktivne sile (težina, vučne sile) od reaktivnih sila veza (normalne reakcije, sile trenja).
) za određivanje zakona kretanja ili sila koje uzrokuju kretanje. Materijalna tačka mase
Mehanika 3 se često smatra jednim od najizazovnijih ispita na tehničkim fakultetima. Dok se Mehanika 1 bavila statikom, a Mehanika 2 kinematikom tačke, nas uvodi u svet dinamike krutog tela, oscilacija i lagranževe mehanike.

Start with from each major topic. Use the step-by-step method outlined above. Within 4–6 weeks of consistent practice, the logic behind every zadatak will become clear.
